It’s going to be an interesting week on the Hill as we’ll hear from the various military service chiefs as lawmakers question them about whether it’s time to repeal DADT — or doing so is somehow too disruptive. (WaPo):

But lawmakers, who are divided on whether to end the ban, say they want to hear from the service chiefs. They are the ones who would be in charge of putting any changes in place and responding to any fallout.

“The armed forces have always placed military effectiveness above individual needs,” said Rep. Gene Taylor, a conservative Democrat from Mississippi who says he is unconvinced that the ban should be lifted.

“This is one of the core concepts that has made the U.S. military one of the most effective combat forces in history,” he said.

While Mullen says he believes the ban should be lifted, he has said he can’t speak for the service chiefs other than to say they support Gates’ yearlong assessment.

The service chiefs are scheduled to testify separately throughout the week, with the Army’s Gen. George Casey and the Air Force’s Gen. Norton Schwartz going first on Tuesday. Marine Corps Commandant Gen. James Conway, who is said to oppose changes to the policy, will testify on Wednesday.

But yet another military voice has come forward signaling that action needs to be taken in today’s WaPo, showing that the the likes of John McCain, Rick Santorum and Elaine Donnelly are finding it hard to present any sane argument why DADT needs to remain in place. Here’s Gen. David Petraeus:

The U.S. commander overseeing troops in Iraq and Afghanistan says he’s not sure that troops in the field care about the sexual orientation of fellow service members. Gen. David Petraeus says he’s served alongside gays and lesbians, and what matters are someone’s skills and smarts.

Petraeus tells NBC’s “Meet The Press” that he supports Defense Secretary Robert Gates’ plan to study how the ban could be repealed. Advocates for a quick repeal have said the yearlong review is a stalling tactic. But Petraeus says it’s a good idea to look at potential problems.

Petraeus has not shared his personal opinion on DADT repeal yet, but will do so when he heads to the Hill to testify later in the spring.
